Dear Folks,
We need to fit the model y~x assuming there are random errors in both
x and y. Numerical Recipes (Press et al.) have two useful functions,
fitxy and fitexy, which handle cases of unspecified and specified
errors respectively.
Are there equivalent functions in base R or a installable package?
Alternatively, has anyone written a wrapper to provide an interface to
a library of Numerical Recipes routines constructed for Linux?
Kind regards,
Marc
